FIREPROQF BLIND.

SPEGIFIQATION forming part of Letters Patent NO. 685,480, dated. October 29, 1901.

' Application filed September 24, 1900. Serial No. 30,984. (No'modeld To all whom it may concern:

Be it known that 1, WILLIAM RAYMOND KINNEAR, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new anduseful ImprovementsinFireproof Blinds and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. p

The object of this invention is to provide means whereby fireproof blinds can be raised when needful to allow the throwing of Water into the building.

In my drawings I show a rolling blind or curtain and my present invention adapted thereto.

My invention resides in a bladed wheel, with gearing between the shaft thereof and a curtain or blind roller, said wheel adapted to be driven by the stream of water from a firemans hose to turn the roller and wind up the blind.

In the drawings referred to, Figure 1 is a side view looking toward the left of Fig. 2, and Fig. 2 is a front View, partially in section.

In the views, 1 designates the blind, and 2 the roller to which the blind is attached and upon which it is rolled. On one end of the shaft of the roller 2 is a large gear-wheel 3, that is engaged by a small pinion 4.. Journaled near the same end of the roller is a bladed wheel 5, having its inner side inclosed with a casing 6, so that a part only of the wheel is exposed at the front or outer side. Fixed on the shaft of the bladed wheel 5 is a pinion 7. Journaled between the pinion t and the pinion 7 is a large gear 8, hav ing on its shaft a smallpinion 9, so that the pinion 9 can mesh with the pinion I and the large gear 8 mesh with the pinion Tom the bladed wheel. Now when the bladed wheel is impinged by an upturned stream of water from a firemans hose it is driven and its motion imparted to the blind roller, thus winding up the blind.

In practice the fire-resisting blind will be normally Wound up and so held by a readily fusible device. When fire takes place either within or dangerously near the building, the blinds will drop to close the windows. If the fire be outside the building, there will be of course no occasion for raising the blinds, and the blinds Will subserve their function of excluding fire and sparks and also prevent the glass panes of the window from being broken by heat, falling timber, bricks, 850.; butif the fire occurs within the building it will be expedient or necessary to throw water into the building; hence the reason for my present invention. It is also to be observed that it willbe necessary to provide means to au-.

tomatically catch and hold the blind up after it is raised by the stream from the firemans hose, and in putting up my described blinds I provide such device.

What I claim, and desire to secure by Let bladed wheel adapted to be driven by'a stream of water from a firemans'hose, a casing partially inclosing said bladed wheel, and gearing intermediate of the bladed wheel, and the blind-roller for transferring the motion of the bladed wheel to the blind-roller, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
